Abstract
The invention discloses a kind of incompressible and stretching spring, including outer spring body, also include the resilient sleeve of parcel spring, also include the outer base for being arranged on outer spring both ends, also include the sleeve pipe and inner sleeve being arranged in outer spring, also include being arranged on the inner spring that sleeve pipe and inner sleeve cross at space, for outer spring in horn-like, both ends diameter is more than interlude diameter；The lateral surface of outer base is convex dot shape, and the cross sectional shape of sleeve pipe and inner sleeve is L-shaped, and L-shaped inside pipe casing is provided with lower end interior base, and set upper side is provided with upper end interior base in L-shaped.Run on the same axis in compression stretching the invention enables spring, will not be distorted deformation, have during compression stretching maximum spacing, and the collective effect of outer spring and inner spring can recover original-shape faster, security when spring uses is ensure that, service life is more permanent.
Description
Technical field
The present invention relates to mechanical spring field, the spring of more particularly to a kind of stretch-proof and compression.
Background technology
Spring be it is a kind of utilize elasticity come work machine components.Part is sent out under external force made of elastomeric material
Raw deformation, restore to the original state, be widely used in various mechanical fields again after removing external force.Existing spring is in stretching or in compression
During the phenomenon for breaking or not recovering profile and disalignment occurs, influence customer experience.
The content of the invention
It is high it is an object of the invention to provide a kind of stability, incompressible and stretching the spring of service life length.
The object of the present invention is achieved like this：A kind of incompressible and stretching spring, including outer spring body, in addition to
Wrap up the resilient sleeve of spring, in addition to be arranged on the outer base at outer spring both ends, in addition to the sleeve pipe that is arranged in outer spring and
Inner sleeve, in addition to it is arranged on the inner spring that sleeve pipe and inner sleeve cross at space；
The outer spring is in horn-like, and both ends diameter is more than interlude diameter；The lateral surface of the outer base is convex dot shape；It is described
Sleeve pipe and the cross sectional shape of inner sleeve are L-shaped；The L-shaped inside pipe casing is provided with lower end interior base；Set upper side is provided with the L-shaped
Upper end interior base；The inner spring and sleeve pipe lower bottom base and inner sleeve upper bed-plate are closely coupled.
Compared with prior art, the beneficial effects of the present invention are：Due to the setting of resilient sleeve, elasticity capacity obtains significantly
Enhancing；Due to the setting of sleeve pipe and inner sleeve, spring is not deviated by axle center in compression stretching by guide effect；Due in sleeve pipe
With inner spring device is provided with the space that crosses of inner sleeve, inner spring device can limit stretching for outer spring during work
Long amount and decrement, while can fast quick-recovery original-shape under the collective effect of inner spring and outer spring.Overall structure is simple,
It is easy for installation, and spring running situation effect is good.
As the preferred scheme of the present invention, the L-shaped sleeve pipe and inner sleeve phase internal buckle form the closed space that crosses.
As present invention further optimization scheme, described sleeve pipe and inner sleeve can simultaneously cooperate on the same axis.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein, 1 outer face, 2 outer bases, 3 outer springs, 4 resilient sleeves, 5 inner springs, 6 sleeve pipes, 7 inner sleeves, 8 inner sleeve upper bed-plates,
9 sleeve pipe lower bottom bases.
Embodiment
As shown in figure 1, a kind of incompressible and stretching spring, including outer spring body 3, include wrapping up the elasticity of spring
Set 4, in addition to the outer base 2 at the both ends of outer spring 3 is arranged on, in addition to the sleeve pipe 6 and inner sleeve 7 being arranged in outer spring 3, also wrap
Include and be arranged on the inner spring 5 that sleeve pipe 6 and inner sleeve 7 cross at space；
Outer spring 3 is in horn-like, and both ends diameter is more than interlude diameter；The lateral surface of outer base 2 is convex dot shape；Sleeve pipe 6 and interior
The cross sectional shape of set 7 is L-shaped；The inside of sleeve pipe 6 is provided with lower end interior base 8；The upper end of L-shaped inner sleeve 7 is provided with upper end interior base 9；It is interior
Spring 5 and sleeve pipe lower bottom base 8 and inner sleeve upper bed-plate 9 are closely coupled.
Above-mentioned sleeve pipe 6 and the phase internal buckle of inner sleeve 7 form the closed space that crosses.
Above-mentioned sleeve pipe 6 and inner sleeve 7 can simultaneously cooperate on the same axis.
The operation principle of the present invention is described below, and when being compressed, sleeve pipe 6 and the device of inner sleeve 7 serve guiding
Effect, makes it not offset in the axle center of compression direction, and inner spring 5 is elongated to maximum, the elastic force of inner spring 5 and outer bullet during release
The pulling force collective effect of spring 3, makes it recover original-shape rapidly.When being stretched, inner spring 5 is compressed to minimum, set
The presence of pipe 6 and inner sleeve 7 makes it be restricted in the maximum of stretching, the elastic force of the pulling force of inner spring 5 and outer spring 3 during release
Collective effect, it is set to recover original-shape rapidly.So that spring is unlikely to deform, increases security, extend its service life.
The invention is not limited in above-described embodiment, on the basis of technical scheme disclosed by the invention, the skill of this area
Art personnel are according to disclosed technology contents, it is not necessary to which performing creative labour can makes one to some of which technical characteristic
A little to replace and deform, these are replaced and deformation is within the scope of the present invention.
